I had this idea for a long time that an extension like this would be great, and I stumbled upon SponsorBlock a few days ago.

this the best thing since adblocks, i can finally surf the web without getting brainwashed

I installed this plugin purely out of curiosity, but what a time saver. Even my favourite subs have intros or in-vid ads/sponsor segments and this just flys past them. Absolutely amazing extension.

thx

If you get annoyed at the recent rise of "But first, I have to talk about our sponsor for the day" interruptions in your YouTube videos, this add-on is an actual godsend.
Just like you should use µBlock Origin for the web in general, you should use SponsorBlock for YouTube specifically.
Just remember to support your favorite creators in other ways, whenever possible.
